18 Claims. '1

This invention relates to stoma receivers, sometimes referred to ascolostomy appliances.

Certain operations are now performed on the himia-n body known ascolostomy and ileostorny operations for the flower intestine or theupper intestine respectively, and these operations .require either thetemporary or permanent formation of artificial outlets from theintestine usually through the abdomen. .An outlet so formed is called astoma. The stoma remains. open at-least a considerable portion of the"time and it necessary to provide a receiver for the stoma to take thedigested food material which passes through the same. In manyinstances-the stoma is located near the groin and large and bulkystor areceivers cannot be satisfactoril used unless the rigid parts thereofare duitesmal-l. On the other hand, it is almost necessary and certainlydesirable that thestoma reoeivershave large capacity. While certainstoma receivers have heretofore appeared on the market, thereisadistinct necessity for improvements in the existing construc tions.

It is an ohject'of the present invention toqsr vide a novel and improvedstoma receiver which can be conveniently and comfortably worn with outbeing noticeableunder the ordinary clothing, which will conform to thebody movementa'whi h will have large capacity and yetwvhiehwill have butsmall rigid par-ts so that it can be wvorn close to the groin orelsewhere and which canioe maintained in a sanitary condition ateailtimes.

Another object or the invention is to provide such a stoma receiverwhich includes a comparatively rigid casing which will :fi-t over thestoma and a flexible bag which will hang down below the casing, themouth of the bag being .so located that it can be placedintcommunication with the stoma and the mouth of the bag. being 'ispcsedwithin the casing so that it will baprotccted at all times by the casingto permitthe free flow of waste matter at all times from the stoma intothe bag.

A further object is to provide a .stoma receiver which will not heat upthe body unduly at the point where it is located.

Still another object is toprovide a stoma receiver including a bag whichcanbe easily cleaned, which can be positively sealed, which can beremoved for emptying, and which can be held by the hands of the wearerand emptied readilyby the wearer without difliculty and without dangerof soiling clothing of the wearer.

It is another object of the invention to provide a stoma receiverincluding a bag into which the stoma empties, there being. valve meansassociated with the bag which will permit the ingress of matter intothebag trom the stoma but which at the same time will prevent the egressof matter from the top of the bag.

Another object is to provide a highly sanitary type of stoma receiverincluding a bag formed of flexible, transparent plastic material so madethat the bag Will hangnatutally against the hody of the wearer but yetwhiohha-g can expand as material enters the same so that the bag Willhave large-capacity.

Another object is to provide a stoma receiver which rigid parts of.asmal-l size so that the rigid parts of the stoma. receiver can belocated close to the groin-and yet the stoma receiver will have largecapacity.

The objects and advantages of the present in.- vention will more fullyappear fromthe following description made. in connection with theaccentpanying drawings wherein like reference characters refer to thesame or similar parts throughout the various views and in which:

Referring first to the embodiment of the invention shown in Figs. 1 to14, there is provided, in accordance with the invention, a casing formedof relatively rigid material and including an inner casing section A andan outer casing section B. The inner casing section A is of circularshape in side elevation. In inwardly spaced relation from its peripheryit is provided with a suitable stoma receiving opening lii, which isshaped to receive a stoma and is usually circular as shown although insome instances it may be of somewhat oval shape, depending on the shapeof the stoma of the individual that the receiver is adapted to fit. Theinner surface of the inner casing section A is preferably somewhatconvexly formed as shown and this surface is made quite smooth. At itsperiphery the inner casing section A is provided with an outwardlyextending grooved flange 20. Inwardly from the flange 253 andcircumscribing the stoma opening 19, the inner casing section A isequipped with an outwardly extending grooved flange 2|, the groove beingformed in the exterior portion of this flange 21. A small gas vent 22 iscut through the base of the flange 2| inwardly from the groove thereof.

The outer casing section B is of somewhat greater than semi-circularshape in side elevation and it is dished at its inner side. It has anarcuate grooved fiange 23 adapted for cooperative removable interlockingengagement with a portion of the grooved flange 2E! of the inner casingsection A. When the two casing sections are so interlocked, a portion ofthe outer casing section B overlies the stoma receiving opening is? ofthe inner casing section in spaced relationship utwardly therefrom forthe purpose of protecting this opening and preventing closing of thesame by the clothing of the wearer. The two casing sections aresecurable together by springing the outer casing section B slightly, thematerial employed for making the casing sections being preferably atranslucent or transparent plastic having enough elasticity to permit ofsufficient distortion of the outer casing section B to engage anddisengage the same from the inner section.

It will be seen that the outer section B closes a portion of the innercasing section A and normally this closed portion is placed uppermost,leaving a slot 24 in the lower portion of the casing and between thelower edge of the outer casing section B and the outer portion of theinner casing section A. The outer casing section B has a circulardepression formed in its outer portion With a button 25 projectingoutwardly from the center of this depression, and this button anddepression are for the purpose of permitting attachment of the casing toa belt 26 carrying an adjustable buckle 2'! at one end and a buckleengaging hook 28 at its other end. This belt is adapted to fit aroundthebody of the wearer, as around the waist, and it has a buttonhole 29formed by slotting a portion thereof, whereby the button 25 may beengaged with the belt. The casing section B is depressed adjacent thebutton 25 so that the belt will fit within this depressed portion tolimit the thickness of the combined casing and belt.

For use with the casing thus described, there is provided a bag 0 ofspecial construction. This bag is preferably formed of flexibletransparent or translucent plastic material, and it is either molded orproduced by dipping a form into the liquified plastic. The bag C has acircular mouth portion at integrally connected with a ring 3| and thering and mouth portion are adapted to releasably engage the flange 2| ofthe inner casing section A within the groove of this flange. Assumingthat the ring 3| of the bag is disposed in a vertical plane, the bagprojects downwardly therefrom in the same general plane as the planewithin which the ring is disposed. In other words, the mouth of the bagis at one side of the bag rather than at the top of the bag. The widthof the bag is reduced somewhat below the mouth 53o to form a neck 32,which is received within the slit 2G aforementioned. Below the neck 32the body 33 of the bag is enlarged laterally until the bag is againreduced in width near its lower end to form a reduced outlet portion 34,the lower end of which is open to form an outlet 35 for the bag. Theneck 32 and the body 33 are provided with corrugations 36, thesecorrugations being provided for several important purposes. Thecorrugations cause the bag to assume small size when not filled orpartially filled but yet permit the distention of the bag so that itwill have large capacity as the bag is filled. The bag normally hangsfrom the casing formed by the two casing sections A and B as indicatedin Figs. 2 and 10, and of course the bag will rest against a portion ofthe body of the wearer. The corrugations 36 formed in the bag permit airto work between the bag and the body of the wearer, thereby keeping thebody cool at this point and preventing undue sweating and heating of thebody. In other words, the ribs of the corrugations 36 are the only partof the bag which come in contact with the body and as a result there ismuch less discomfort to the wearer than in the case of a smooth surfacedbag.

The ring 3! has sufiioient elasticity to permit it to be readily carriedover the outer portion of the flange 2! to fit the bag onto this flangeand to permit removal of the bag from the flange. In order to permit ofready removal of the mouth of the bag from the flange, a small tab 3?secured at its upper end to the ring 3! is provided whereby thereinforced portion of the bag can be pulled upon to disengage the mouthor" the bag from the flange. To close the lower end portion 34 of thebag and'yet to permit easy emptying of the bag without danger of soilingthe clothes of the wearer and by use of only the two hands of thewearer, I have developed a special construction. A flexible tab 38 hasan upper circular portion which is molded into the inner side oi the bagnear its lower end and this tab carries at its lower end a half snapfastener 39 which engages with another half snap fastener 40 attached tomeans the upperendrof a. second=flexible tab all, the.

tab 41% having an enlargementrZ atrits lower end. A channel member 43 ofspringconstruction and made of metal or hardened plastic has aprojecting flange 4'5 at one side thereof provided with a keyway slot 45within. which the tab 4| slidably fits. Accordingly the channel memberA3 can slide upwardly or downwardly on the tab iii, the enlargement 42preventing thetab from being pulled out of the keywayI slotunintentionally. If it should be desired to detach the channel memberfrom the tab 4!, howeventhis can be readily doneby compressing the tabinto one portion or" the keyway slot 45 and working the tab through theentrance notch of the keyway slot. The tab ii is made longer than thenormal spacing between the lower end of the tab 38 and channel member t3when the outlet of the channel member is closed to allow for readysecuring of the channel member to the lower reduced portion of the bag.The sliding connection between the tab 4! and the channel member permitsthe channelmember '33 to slide upon the tab ll without bowing the taband forming a bunch below the clothing of the wearer when the outlet 35is closed. The channelmem-- ber 43 has a roller 46 connected to one endthereof by a pivot fill and this roller carries a handletB. Theflanget't and the opposing flange ofthe channel member are curved towardeach other slightly to form a spring entrance mouth which willresiliently receive the" roller 56-. By

carrying the lower reduced portion 8 3 of thebag C around the roller 66in a bight and then swinging the roller it into the channel member 43through its entrance mouth, the channel member and roller 115 will havea clamping action on the bight of the reduced lower end portion 34 ofthe bag to tightly secure it and prevent any leakage of the contents ofthe bag C through the, outlet opening 35 while not injuring the lowerend portion 34 of the bag. Opening and closing of the lower portion.ofthe bag can be accomplished by one hand of the wearer either while thebag is attached to the casing or when it is detached and held by theother hand of the wearer. Thus the fingers of one hand may grasp thechannel member 43 andthe thumb of the same hand can be engaged with thehandle 48' to swing the roller 46 out of the channel of channel member43. The strap connection between the channel member 33 and the bagprevents the clamping mechanism. being. lostwhen.

the lower end of the bag has been opened.

In some instances it may be desirable to use with the stoma receiver avalve. member. D to permit the ingress of matter into the. bag, C while,

preventing the back flow of. matter through the mouth of the bag. Asshown in Figs. 2, 7, 8, and.

9,, the valve member D comprises a. dome-shaped body having a groovedflange at its periphery, the groove being on the external side of thisflange and the grooved. flange engaging the portion of the inner casingsection A surrounding thestoma receiving opening 19. The valve member.is made preferably of. flexibleplastic or rubber andv it has. a flatdischarge spout portion 48 terminating in,

an. outlet 511. The side walls. of thespoutportion t9 are very narrow sothat rather wide. lips are formed, the, lower portions of which. arenor-- mally in contact with each other topreventthe re-entrance ofmatter back into the dome portion of thevalvemember after this matterhas once passed through the spout portion :19. The lips of thevalveimemberarediagonally cut as shown in:.Figs;i"7xand 8. inasmuch aswith such a cori valve. are provided With rounded contours 5i pro--ducing the back-sealing action.

In Figs. 16 and 17 there is shown a bag F similar in all respects to thebag C previously" described with the exception that a valve mem berG isformedintegral with the upper portion ofthe bag. This valve member G ismuch on the order of the valve member D firstdescribed with theexception that it is larger and the edges of the domed portion of thevalvemember G are integrally formed with the mouth portion of the bag F.

In certain instances where the stoma is located very close to the groin,it may be desirable to provide an inner casing section H, such as thatshownin Fig. 18, which is in all respects similar to the inner casingsection A previously described withthe exception that the stomareceiving. opening 52 formed in the casing section I-I eccentricallydisposedrelative to the periphery of the inner casing section instead ofconcentrically located as in the case of the inner casing sec tion A.The eccentric disposition of the opening 52' makes it possible to fitthe casing very close to the groin.

In Figs. 2 and lo a portion of the skin of the human body is designatedbythe letter J and attached to this skin is a stoma S, it beingunderstood that the stoma S willconnect with either the large or smallintestine. In mounting. the stoma receiver on the body, a suitableabsorbed pad 53-, having a central aperture through which any protrusionof the stoma extends, isplaced against the skin, and thereupon thereceiver in its assembled condition will be applied against this pad atthe exterior thereoiwith the stoma in direct communication with the domeportion of the valve member if a valve member such as D, E, or G isemployed, or'in direct communication through the stoma receiving opening19 or 52 with the upper portion of the bag C if no valve member is used.The absorbent pad 53' is preferably made of cellulosematerial. havinghigh absorbent qualities and having numerous plies, preferably backed bycrepe moisture repellant material. This pad cushions the effect of thecasing'against the body and it prevents the spread of the waste matterdischarged through the.

stoma S to the skin adjacent the stoma. After the belt and casing havebeen applied and the belt'Zfi has beerrmounted. on thebody, the'belt canbe adjusted so that the button 25 be, conveniently received in thebuttonhole whereupon the device is ready for service.

As'the major part of the: bag does. not fit within the casing consistingof the inner and outer sections'A and B or H and B, as the case. may be,the" rigid parts ofthe" receiver can .be made quite small and yet thebag. will have large capacity. The major part of' the receiver willyield" with bodymovements so that the device will be unnoticeable whenworn under the clothes and also. the receiver can be used in conjunctionwith a stoma located very close to the groin without? inconvenience tothe" wearer.

The material dlscharged from the stoma can readily flow into the bag andthe corrugations of the bag will allow the bag to distend as materialflows into it so that, while the bag occupies but small space when notfilled, it can expand and a large volume of material may be accommodatedwithin the bag. If one of the valve members D, E, or G is employed, thiswill prevent the back flow of material through the receiving mouth ofthe bag while at the same time permitting the free ingress of materialemptying from the stoma. When it becomes necessary to empty the bag C,this can be readily accomplished by the two hands of the wearer. Thevent 22 will permit the discharge of gas.

Preferably the bag and the inner and outer casing members A, B, and Hwill all be made of transparent or translucent material which canbeeasily cleaned and sterilized so that the device can be maintained insanitary condition at all times. The parts can be readily taken apartfor cleaning.

It will be seen that a highly satisfactory stoma receiver has beenprovided having many ad vantages.

It will of course be understood that various changes may be made in theform, details, arrangement, and proportions of the various parts withoutdeparture from the scope of the present invention which, generallystated, consists in the matter shown and described and set forth in theappended claims.
